So when I turn the on the heat or ac i get nothing but hot air all the time. It doesnt matter if the ac button is on it still blows hot air. Any suggestions of a remedy.

Check the circuit breakers/fuses

If there is a similar relay in there for something else that's pertanent for the car to run, swap it out

So wait, the blower works, but you get hot air all the time no matter where you turn the temperature knob? Or is it that your A/C just doesn't work and you can get cool outside air but not cold air?

If its the first one, I'd tell you to pull the hvac controls and make sure everything is still connected on the back side. If you have nothing but heat, then the door inside the hvac housing is either busted or the control for it is.
